Title: Transistor
Inventor: MORI SADAYUKI
IPC: H01L29/78
Filed: 1994-05-02
Abstract: PURPOSE:To improve the withstand voltage between a drain and a substrate in a transistor when it is intensively inverted. CONSTITUTION:The upper surface of the neighborhood 42b of the second contact part, which is the contact part with a channel stopper region 52 in a gate region 42, is covered by the second extension part 49b of a thick field oxide film 40. Accordingly, as the neighborhood 42b of the second contact part is hardly inflicted by the voltage applied to a gate electrode 46, the density of a hole is low. On the other hand, as a substrate 34 is earthed to the ground through the channel stopper region 42, the contact part between the channel stopper region 52 and the channel 50, which is inverted to P-type, are in P-N inverted junction. Accordingly, the withstand voltage between the drain region 38, in an intensively inverted state, and the channel stopper region 52 (substrate 34), which depends on the density of the hole of the channel 50 located on the contact part between the channel 50 and the channel stopper region 52, can be enhanced.

Abstract: PURPOSE:To eliminate necessity of an exciting power supply for a transformer at an upper stage by forming a series resonance circuit with a plurality of transformers integral with a variable reactor and a capacitive load. CONSTITUTION:A series resonance circuit is formed of transformers 11-13 integral with variable reactors 11a-13a and a capacitive load 14, the transformer 11 at an initial stage is operated as a power supply, and the transformers 12, 13 of a rear stage are operated at variable reactors 12a, 13a as high voltage variable reactor.

In this manner, it can eliminate the exciting winding of the transformer of the next stage and also eliminate the transformer for power supply of the series resonance. The transformers of the respective stages and the variable reactors may be the same type so that the high voltage terminal is of one side type (other terminal is the same potential as the case), which can employ the conventional general transformers resulting in the economization of the system.

IPC: G02B5/30
Filed: 1988-04-15
Abstract: PURPOSE:To obtain the inexpensive polarizing element which absorbs no light by providing a means which separates incident luminous flux into two linear light components, converges the components on different positions, and rotates the plane of polarization of one obtained linear polarized component. CONSTITUTION:A double reflection layer 102 made of an optically anisotropic material separates the incident light beam into an ordinary light beam 103 and an extraordinary light beam 104, which are converged temporarily on the different positions by using a lens 105 without overlapping spatially with each other. The separation angle of the two polarized light components by the double refraction layer 102 is determined by the angle of a taper provided beneath the layer and, for example, when the double refraction layer is formed of double refraction materials whose refractive indexes to the ordinary light and extraordinary light are 1, 5, 2, and 0 and the angle of the taper is 10 deg., the separation angle of the ordinary light and extraordinary light is about 5.2 deg.. Here, when the plane of polarization of the extraordinary light 104 is rotated to meet the plane of polarization of the ordinary light 103, the incident light beam is all converted into luminous flux 108 having a specific polarizing direction without being absorbed.
